The MCP23017 provides a 16-bit general-purpose parallel I/O expansion for the I2C bus. It consists of multiple 8-bit configuration registers for input, output, and polarity selection. The system master can enable the I/O as either inputs or outputs by writing I/O configuration bits (IODIRA/B). The data for each input or output is kept in the corresponding input or output register. The polarity of the input port register can be inverted with the polarity inversion register.
Package Includes: 1 x CJMCU-2317 MCP23017 Serial Interface Module
